Name of the Vulnerable Software and Affected Versions redis-server versions prior to 8.6.3

Description Redis is an in-memory data structure store. The RESTORE command fails to properly validate serialized values. An authenticated attacker with permissions to execute this command can provide a crafted serialized payload, triggering invalid memory access which may lead to remote code execution.

Recommendations Update to version 8.6.3. Restrict access to the RESTORE command using ACL rules as a temporary workaround.
